Question

construct triangle PQR such that QR is equal to 5 centimetre, angle Q is equal to 45 degree and Angle R is equal to 30 degree find the measure of angle p . Step by Step​

Answer 1

Step-by-step explanation:

Draw a rough sketch of the triangle and mark the given dimensions .

Draw a line segment of QR=5cm.

At Q, draw a ray QX making an angle of 45° with QR, with the help of protractor.

At R, draw a ray RY making an angle of 30° with QR .

Point P has to lie on both the rays, so P is the point of intersecting of the two rays.

The triangle PQR is the required triangle.

Finding the third angle: Subtract the sum of the two given angles from 180°.
